GData transmission
The SC-8850 can use Exclusive messages to transmit internal settings to other devices. There
are two types of Exclusive data transmission; Individual Parameter Transmission (page 233)
in which single parameters are transmitted one by one, and Bulk Dump Transmission (page
242) in which a large amount of data is transmitted at once.
The Exclusive message used when transmitting GS format data has a model ID of 42H and a
device ID of 10H. (The SC-8850 allows you to change the Device ID setting.)
❍Request data 1
RQ1 (11H)
This message requests the other device to send data. The Address and Size determine the
type and amount of data to be sent. There are two types of request; Individual Parameter
Request which requests data for an individual parameter, and Bulk Dump Request which
requests a large amount of data at once. In either case, the "Data Request 1 (RQ1)" message
format is used, and the Address and Size included in the message determine the type and
amount of data that is desired.
For Individual Parameter Request, refer to 3. Individual Parameter Transmission (page
233).
For Bulk Dump Request, refer to 4. Bulk Dump (page 242).
When a Data Request message is received, if the device is ready to transmit data and if the
address and size are appropriate, the requested data will be transmitted as a "Data Set 1
(DT1)" message. If not, nothing will be transmitted.

F7H EOX (End Of Exclusive)
* The amount of data that can be transmitted at one time will depend on the type of data,
and data must be requested using a specific starting address and size. Refer to the
Address and Size listed in Section 3. Individual Parameter Transmission (page 233).
* Regarding the checksum, please refer to Section 5 (p.245)
❍Data set 1 DT1 (12H)
This is the message that actually performs data transmission, and is used when you wish to
transmit the data.

* The amount of data that can be transmitted at one time depends on the type of data, and
data can be received only from the specified starting address and size. Refer to the
Address and Size given in Section 3. Individual Parameter Transmission (page 233).
* Data larger than 128 bytes must be divided into packets of 128 bytes or less. If "Data Set
1" is transmitted successively, there must be an interval of at least 40 ms between
packets.
* Regarding the checksum, please refer to Section 5 (p.245)
